FCB is short for the high efficient technique of flux and copper backing with one-side welding both-side forming.

This paper presents a new type of Fe-base wear-resistant materials-FCB alloys.

It was the first time in Shanxi Province to carry out the FCB test on No.

FCB test is to inspect the capability of the unit as soon as it is tripped from the network with transient load rejection to the auxiliary load it is automatically recovered and operated stably under the coordinated operation mode of big load.

It focuses on the generation of some important signals closely related to Coordinate Control System (CCS) and DEH system, such as CCS instruction, RB, and FCB signals, and the mode of interrelation between these signals and DEH, and the action to DEH instruction signal.

This paper describes the features of Yangcheng power plant and special meaning of FCB function in coordinating control system,explores the enhanced plan for solution of existing problem in function of FCB and evaluates FCB test.

This paper analyzes how to take the mechanical modification for the central swivel joint and FCB shield machine according to the requirement of FCB Shield machine frontal detection,installs GPR on the cutter disc and makes cutter disc stress analysis,carries on the wiring for data transmission through the scene mapping.
